Hi guys. I have a big big problem. Just attached a new system, and I have a big wedding tomorrow. System blends nicely in terms of lenght and density and all but for some reason this one came quite reddish. My hair is darkish brown but very ashy matte, without any strong color. The reddish streaks pop out very noticeably inbetween natural hair. It looks quite wiggish.

What last minute tricks can I pull off to help mask the brass color a bit??

Would be incredibly grateful for any help, I have nowhere else to turn than you guys
